Encoding
Morse Code Translator
Translate text to Morse code and decode Morse back to letters. Supports letters, digits, punctuation, and word separators.
Encoding
Caesar Cipher / ROT13
Encode or decode text with the classic Caesar shift cipher. Adjust the shift from 0 to 25 with a slider, jump to ROT13, or brute-force all 26 shifts to reveal a hidden message.

工具介绍
Encode or decode text with the classic Caesar shift cipher. Adjust the shift from 0 to 25 with a slider, jump to ROT13, or brute-force all 26 shifts to reveal a hidden message.
工具概览
The Caesar cipher shifts each letter by a fixed number of positions in the alphabet. ROT13 is the special case where the shift is 13, which makes it self-inverse (encoding twice returns the original text). Digits, punctuation, and whitespace are left unchanged. This is a classical cipher intended for puzzles and learning — it provides no real cryptographic security.
使用场景
- Use Caesar Cipher / ROT13 when you need fast encode and decode text with a classic caesar shift cipher. includes a slider, a rot13 preset, and a brute-force preview of all 26 shifts.
- Handle encoding workflows directly in the browser with no install required.
- Support SEO long-tail intent by covering quick checks, troubleshooting, and one-off conversions.

常见问题
Is the Caesar cipher secure?+
No. It's trivially broken by trying all 26 shifts, which is exactly what the brute-force panel does. Treat it as a learning or puzzle tool, not real cryptography.
How do I decode an encoded message?+
Either use the Invert button to flip your current shift, or slide through the values until the output looks like readable text.
Does it handle non-English alphabets?+
The shift only applies to the 26 letters of the basic English alphabet. Other characters pass through unchanged.
